'.lflw Schedule referred to `in these Lettera Patent maldng part of the meme.'

Be it known that I, TowNsnNn Poonn, of Scranton, in the county of Luzerne, 'and State of Pennsylvani'a, have invented certain new and useful Improve- 4ments ou Fluid and Gas-Meters; and l' do hereby declare that 4the following is a full, clear, and exactdescription thereof, reference being had to the'accompanying drawings, making a part of this specification, in whiehg Figure 1, sheet 1, is a diametrical section through oneform of my improved meter, showing the several parts which actuate Athe valve in the position they would oceupywhen the valve is closed, and its disk is about to rise and collapseV the expansible receiver,

` or bellows.

Figure v2, sheet 1, is asimilar view of the same parts, in their properpositions when the valve is ope'n and the receiver about to expand and allow water to pass through the valve-opening.

\ Figure 3, sheet 1, isla bottom view of the valve and its mechanism.` v

Figure 4, sheet 1, is a side view of the valve audits mechanism. i

Eigure 5, sheet 2, is a diametrical section through.`

a meter, the valve of which .is controlled by mechanism dilen'ng somewhat in its construction from that shown n sheet l. In this figure the .fralve is shut,

and the parts in proper position for causing the re ceiver, or bellows to collapse, by the influx of water Figure 6, sheet 2,-is a diametrical section, taken through the meter at right angles to the sectional `plane ot' iig. 5, indicating the valve open, and the' parts in position, for allowing the receiver, or bellows to descend, by its own gravity, through the body of water beneath it.

` 4 Figures T, 8, and 9, are details oi' three parts ofthe valve-mechanism of tigs. 5 and 6. 4

Similar letters of reference indicate corresponding parts in the several figures of both sheets of drawings.v p e This invention relates to certain novel improvements on the actuating-.mechanism of meters, which are-:de-

signed for indicating, by measure, the quantity lof tluid or gas caused to pass through them.

The object of my invention is mainly to cause `an uninterrupted current of water or other liquid, or a current ofl gas, under ahead,` to communicate a reciprocating motion, with regular strokes, to a disk, piston, or plate, arranged within a case'through which the liuid is conducted', :1nd to this c|ul,l employ, within a case of, suitable construction,an expansible recadrer, or bellows, or the equivalentthcreof, through the valve-opening of which fluidy is required to pass, on its way to the outlet of said case; and I connect to the valve-stem and disk of said receiver, or bellows,

certain levers, weights, and latches, which are so coustructed and combined thatthey will automatically operate .to open and locl open the valve, when the receiver has been properly collapsed by the-pressure of entering fluid on onev side of its disk, and thereby allow thereeeiver to dilate, by the gravityof its valve-- disk and appendages, and also automatically. operate to shut the said valve when the receiver has been properly dilated, and keep it shut until it is again collapsed. In this manner, 'I cause the valve-disk to receive a reciprocating lmotion, with regular strokes, which can he transmitted, in any ,convenient manner, to suitable mechanism that will record the strokes, and consequently the quant-ity of fluid passed through the case of the meter, all as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I will describe its constrnction'and operation.

In the'aecompanying drawings-- A-represent a case, within which work the improved devices, which I shall hereinafter describe.'

This case is preferably coustruetedof a cylindrical form, but may be made of any other form, with a removable cap, or cover, A', secured, by flanges .and

bolts, to the upper end of the body, A, and having a glass plate, B, secured, air-tight, within its reduced cylindrical portion, through which registering-mechanisin can at any time be seen.

The outlet-opening, O', is also made through this upper section, A', of the case. i

The lower section, A, is constructed with an inlet, C', and also with vertical grooves, p p, arranged diarnetrically opposite each other, and designed to serve as guides, as will be hereinafter shown.

Within thiscase is 'a circular receiver, or bellows, which may be made of any suitable material, and which is coniined, at its upper open end, between the flanges of the two parts A Af, of the case, as shown in figs. land 2, thereby making a packed joint at this point.

The lower end of the receiver, or bellows, is secured air-tight.to the top of a circular plate, E, through the centre of which is `an opening, i, for 'the passage upward of' water .or other fluid.

Surrounding this opening i, `andV extending down from the bottom ot the disk E, isa collar, c, the lower end of which serves as a valve-seat, for a verticallymovable valve, g. This valve is prepared so that it will close tightly, and prevent the passage of water or 'gas when it is closed, and its stem, h, is held in proper position by tle twohridgesj and K, as shown in figs. l and 1n practice, I shall make valve-stein hof a substance which will not readily corrode, so that it will not work hard from this cause. e

When the valve gisopen, it rests upon a seatformed by the depressed bridge, or stirrup l, as 'shown in iig.

-the inilowing'water and a loaded lever, P P', as shown in fig. 1. l I

The valve. g has studs, 't-t, projecting from its circumference, diametrically opposite each other, as shown in iig. 3, to which studs .the lforked ends of a loaded lever, P P', are loosely attached.

Thisleveris pivoted tothe stirrup, or pendent bridge K,at s, so that when its loaded end P' is released from its hooked catch, N', and it is not ccunterbaianced by a' loaded lever, L L', the weight P' will cause the valve g to rise to its seat, as shown, in iig. 1.

The arms P P, ofthe loaded lever, are arranged on opposite sides of the stirr'np Kyand curved outward,k as shown in iig. 3, and the loose or forked connections of' these arms P P, to the studs t t of the valve g, will prevent the valve-stern h from liability to bend'in consequence of being moved by arms-which vibrate.

i On the opposite side of the valve gto the loaded lever P P',=and arranged in line therewith, is another loaded lever, L L', the object of which is to open valve g, at the termination oi `the upward stroke of the valvedisk E, when the receiver, or bellows has fully collapsed.

This lever, like the one described for closing'valve g, at the termination of' the downward stroke of' valvedisk AE, is constructed of twoarms, L L, with a weight, L', on their outer ends.` l

The arms L L are curved around the arms P P, as shown in fig. 3, and connedted loosely to the pivot-piu s, which, as above shown, is the fulcrum of the loaded lever P P', and by means of the forks y y, formed on arms-L L, these arms are loosely attached to the studs t t, on the valve-stem, so that when the catch M is tripped by the shoulder, or abutment e', or its equivalent, on case A, and the lever L L' released, its loaded end, L', will drop, and open the valve g, and also lift the loaded end of the lever PP high enough to be caught and held by the hooked nose n,catch' N thereby opening and locking open the valve, so that it cannot casual y return to its seat until the proper time 4for it to do so.

Thearms of lever L L'- will rest upon the valvestuds t 1,' until the disk E descends far enough to allow the loaded end, L', to land upon the bottom of the case A, when the disk will further descend, until the valve gis shut.

The valve g is shut by the force of the inflowing fluid through aperture O', together with the weight P', when this weight is released from its catch by the tail n, of the latter, coming in contact with the abutment o, near the bottom of case A, but this does not take place until the loaded end'cf lever L L' is engaged with the hooked nose d, of catch M, as shown iu fig. 1.

Immediately upon the shutting of' valve g, the disk E commences to' ascend, by the pressure or the inflowing fluid against its bottom, and continues to ascend until the tail e, of catch M, impinges a ainst the abutment e', and thus releases the leverLL' rom the hooked nose d of said catch, when its loaded end will drop, and open' valve g, and lock it open again, as abovedescribed'.

Both catches M and N' are so connected, by their respective pivots, to the bottom of disk E, that their hooked, o r latching-ends preponderate, and will automatically catch under their respective levers atthe proper times.

It will be seen, from the above description, that fluid cannot pass through the case A A' without first entering the receiver, or bellows D, through vthe valve-opening s', in order to do which the pressure of the fluid must raise the disk E to the full length of? its ascending stroke, so as to own the valve g. When this is done, the weight of'- the said disk and its appendages will cause them to descend through the fluid until the valve is again sluit, when the disk will again rise.

I have not represented mechanism for registering Y' of case A, and

the strokes ofthe disk E, as any well-known mechanism, adapted for such purpose, may be used, and con- `nected in any convenient manner with the lsaid disk.

I prefer to arrange such mechanism as may 'be adopted within a perforated case, depending from the cover A', within the receiver D, and directly below or opposite the transparent plate B, although l. do not confine myself thereto. v

The perforated case isindicated by dotted red lines in, figs. 1 and 2, and will act as a strainer, to prevent foreign substances in the fluid from entering and interfering with the working of the registering-mechaniam. By thus having the registering-mechasism work within the water in the receiver, l avoid the objections attending a stuiling-box for the device used to transmit the strokes, or pulsations of the disk E to said mechanism.

he figures represented on sheet2, ofthe drawings, showv a contrivance which will effect the same results, and which operates upon the same principlev as the contrivance above described. y

A A' represent the case of the meter.

B, they glass plate, which is confined in the cover,A

C is thc outlet for the fluid, and

C', the inlet therefor.

D is the expansible receiver, or bellows, and

E' is the disk to which its bottom edge is secured air-tight.

The valve-opening 'i and scat c are arranged in the centre of the disk E, and the valve g' has 'a vertical movement in opening and closing.

All of these parts may be constructed as described for similar parts `on sheet 1.

The valve-stem h.' is guided by the bridge U and the depressed stirrups S.

The bridge U should be depressed like the bridge j, in iigs. 1 and 2.

Between the bottom of valve g' and a'disk, T, which is fast cn valve-stem h', the rounded inner ends of two loaded levers, Q R, Q Rz, are placed so that when the loaded ends, Ri R, are released from catches N' N', and drop, as shown in fig. 5,' they will shut' the valve g against its seat, and when the valve is opened, by a weight, R, as will be hereinafter shown, the loaded ends of said levers will he raised, and caught'by the hooks' 2 2, of the catches N N'.

The loaded levers are pivoted, at V Y, to thc slotted stirrnp S, a top view of which iis shown by fig. 8, and the catches N' N' are pivoted to said stirrup, at W W, shown in lig. 5.

The catches Nare both constructed alike, and each cnc is so pivoted, with relation to the catching portion of its loaded lever, as to automatically catch thereunder at the proper time for locking the valve g open at the termination of the ascending strokes of disk E.

To the valve-stem h', and beneath the stirrup S; a. weight, R, is applied loosely, or so as to snide freely for a short distance on this valve-stem;

This weight B consists of a centlal hub, having four arms radiating from it, and arranged at regular distances apart; andfrcm the bottom side of' each arm at or near its outer extremity, are feet, R, which support the weight upon the bottom of the case A, when inposition shown in iig. 5.

Two of' the arms of said weight sa slotted, at d4., to receive through them the cntche. of', as shown m figs. 5 and 7, and two of these arms are slotted, and provided with catching-pieces, 3 3, as shown in figs. 6

.and 7.

in lig. 6, J .lare two hookedeatches, which are connected to the disk E, by lugs, J J', and pivots, 7 7, so as to catch under the pieces 3 3, on two of the arms of weight E, when this weight'is landed on thebotwm thus hold the valve g shut, and allow the said weight whe carried up with the diskllt.

The outer ends, or tails of catches J, work in verti cal grooves, m m, made in the case A, whichvgrooves terminate, at their upper ends, at abntmeuts, 6 6, against which the tails of `these levers impinge, to release the weight R, and allow it to open valve g by its gravity, as shown iu iig. 6.

The catches J J are arranged in a vertical plane, at right angles to the plane of the two catches N' N', and therefore do not appear in the sectional view, lig. 5.

The operation ofthe parts shown in ligs. 1 and 6 is as follows:

Water or other fluid being let into the case A, through inlet U', and valve gf being shut, as shown in iig. 5, the disk E will risc until the tails of catches J J impinge against the abutments 6 6, and release the weight R.,

when this .weight will drop on a unt, or stop, q, on

valve-stem h, far enough to open valve g', as shown in fig. 6. 'When' this takes place, the loaded ends It* of levers Q Q will be thrown np and caught by thc glavitating-catches N' N', thus locking the valve g' open,

'and allowing thevdisk E to descend, while the water passes into the receiver, or bellows D, through the opening fi.

The weight It rst reaches the bottom ol' the case A, and as the disk E continues to descend further, the bevelled inner edges of the gravitating-catchesN N' will impinge upon the outer edges of arms 4 4, and these catches will be moved outward' far enough to release the levers Q Q, and allow their loaded arms valve is opened by a weight, R, which is applied loosely to the valve-stem, so as to drop,- wheu released, upon a nut, q,`on the lower' end of said valve-stem, which latter plan I consider to be the equivalent of the loaded lever as arranged.

Having described my invention,

What I claim as new, and des-ire to secure by Leif ters Patent, s-

1. The loaded levers-P, applied to disk-.E, or its equivalent, and so connected to valve g as to shut this valve at the termination of the down-strokes of said disk, substantially asI described. n

2. The loaded lever L, applied to disk E, or its equivalent, and provided with a gravitatingatcb, M, and so connected to the valve g, and loaded lever P,

as to open this valve at the-termination of the npstrokes of the disk E, substantially as and for the purposes described.

3. The combination of loaded levers and their respective catches, with valve g, and reciprocating -disk E, said parts being so constructed and arranged as to operate to shut valve g, at the termination of the'do'wn-stroke of disk E, and to open and lock open the valve at the termination of the up-stroke of said disk, substantially as described.

4. The combinationof the gravitating-latches and catches, with a reciprocating valve-disk, E, of a fluidmeter, arranged and constructed s0 as ,to automatically open and lock open lthe valve of said disk, at the termination of its up-st'roke, so that the valve cannot casually shut while the disk is descending by gravity, substantiallyas described.
